MILK-COOLER.

To all whom 'it may concern: i

Be it known that I, EMMA L. WALLACE, a citizen of the United States,residing at Halsey, in the county `of Linn and State of f Oregon, haveinvented certain new and usey ject of the present invention to provide acooling apparatus of this kind which can be `easily cleaned and thuskept in thorough sanitary condition, and also to provide imrovedmeansfor supporting thereceptacles 1n the vessel.

A further object of theinvention `is to provide a cooler embodyingcertain novel featuresof construction to be hereinafter de- `scribed andclaimed.

wall of the vessel, and support-`the cover inV open position. A has-and-staple lock for. i o i In the vaccompanying drawings forming a partof this specification- Figure 1 is a plan View of the cooler withthe'cover thereof thrownopen. Fig. 2 is a transverse section with thecover closed. Fig. 3 is a longitudinal section showing the milk or creamholding receptacles within the cooler. Fig. 4 is a perspective view ofone of the holding devices hereinafter referred to. i x

Referring specifically to the drawings, the vessel which contains thec00lin medium comprises a front wall 10, rear an lend walls 11 and 12,respectively, a' bottom 13, and a hinged cover 14. The cover isdouble-inclined and seats on the top edges of the lfrontprear and endwalls, and said cover also hasa depending bottom lange 15 fitting snuglyi against the Iinner surface of said walls soas to make atightinclosure. The hinges of the ,cover areiindicated at 16. In theend wallsof the cover are Ventilating holes 17 to permit the escape of any heatrising from the cooling milk `or cream, and also to allow fresh air tocirculate through the apparatus. To the free ends of the cover areconnected chains 18 which are fastened to the frontthe cover is alsoprovi ed. f

On the bottom of the vessel are transverse strengthening 'stri s 19,vand wooden supports 20 are provi ed on which the vessel lLs removablysup orted. D `At 21 is in icated the inlet pipe of the Speci'cation ofLetters Patent.

cooling agent, said pipe being connected to one of the end walls of thevessel near the top thereof. This pipe may be connected to` a suitablesource of water supply. If running water is not available, the vesselmay be filled through a funnel 22 attached to the inletv pipe. An outletpipe 23 is'connected to the opposite end wall near the bottom of thevessel, and an overflow pipe24 is `also connected to said wall slightlybelow the level of the inlet pipe. The overflow pipe'is connected totheoutlet pipeand the latter is also provided with a valve 25 which islocated between the vessel and the point at which the overflow pipejoins the outlet plpe. i

On the front and rear walls of the vessel, inside the latter, areshelves 26 for the cansupporting frames to be presently described. Theseshe ves are formed b foldin over the material. of which the ront an rearwalls ofthe vessel are constructed, the fold being downwardly along theinner surface of said walls for a short distance, as indicated at 27,and said downward fold vterminates in an outward horizontal bend asuiicient distance to form the shelf, said outward bend terminating in areturn` bend beneath the shelf, thus doubling the same, the end of thematerial being soldered to the shelf. This construction makes the topedges of the front and rear walls perfectly smooth and at the same timeforms strong and rigid shelves. Braces 28 for the shelves are alsoprovided. D The can-supporting members comprlse a frame composed of anlron rod` which 1s 'bent to form an intermediate circular por- 'milk orcream seats in the intermediate circular portion 2 9 ofthe frame, thehandles 34 of the can engaging the top thereof, and holding the can inplace within the frame. On the shelf of the front wall are mounted.latches com rising screw hooks 35 which --are 'adjusta le to engage overthe transverse portion 31 of the frames and thus hold the same down whenremoving the cans therefrom.

The cans 33 have perforated covers 36 in` order to permit the escape ofthe heat which rises from fresh milk or cream, and at the same time toprevent the crea-m'from drying which occurs when standing entirelyuncovered.

The entire apparatus herein described,

except the milk or cream cans', will-be constructed of galvanized metal,and as all parts are readily accessible,l the apparatus can bethoroughly cleaned and kept in sanitary condition. The interior of thevessel is accessible upon swinging the can-supporting frames upwardly ontheir hinges. The cans will be made of extra heavy tin.

I claim: u Y

l. An apparatus of the character ydescribed comprising a vessel havingan inlet and an outlet for a tempering agent, shelves on opposite sidesof the vessel on the inside and below the top thereof, andreceptaclesupporti-ng frames each comprising an inter- I mediatecircular portion, and end portions, one of said end portions beinghinged to one of the aforesaid shelves, and the other end portion beingsupported on the other shelf.

2. An apparatus of the characterV described comprising a vessel havingan inlet and an outlet for a tempering agent, shelves on opposite sidesof the vessel on the inside and below the top thereof, said shelvesbeing formed by bending the material forming- Asaid opposite sides ofthe vessel inwardly and downwardly, said bends terminating inlhorizontal bends at the extremities oi' whleh return bends are made,said horizon.-L

tal and return bends forming the shelves,

and receptacle-supporting frames mounted` on the shelves. In testimonywhereof I aiiix my signature in presence ofltwo witnesses.
